The XmlSiteMapProvider class, which is the default SiteMapProvider provider implementation for ASP.NET, uses the SiteMapNode::Url property as a lookup key, if one is provided for the node (if a URL is not provided, a tracking identifier is generated for the node). Therefore, any SiteMapNode object that provides a URL and is used by the XmlSiteMapProvider must have a unique URL within the scope of the provider.
If no title or description is provided, calls to the Title or Description properties return an String::Empty field.
The following code example demonstrates how to use the SiteMapNode constructor to create a SiteMapNode object by parsing data from a simple text file to build a site map in memory.
This code example is part of a larger example provided for the abstract SiteMapProvider class.
